How your able to drive the car is the most important factor. If you can avoid stop-and-go driving and maintain a constant modest speed you can get great mileage, but if you have to stop frequently and wait minutes at every light then you will struggle to get crappy mileage. Driving short trips where the engine is always cold or heating up you will get crappy mileage.

There's a road in town that I can get over 40mpg if the traffic is light and I hit the lights nicely, but if the traffic is heavier and hit many of the lights then I can drop down to near 20mpg -- same road, 2x difference in mileage.

Coasting down hills means two things.

1) You are out of control of your vehicle
2) You are requiring fuel to me pumped into the engine to keep it idling in neutral, where as if you keep it in gear, the weight of the car is keeping the engine rotating, therefore requiring LESS fuel, than idling.

Bottomline, don't coast downhills.

Elizabeth: weigh the front and rear of your car, then tell us about tire pressures, as you are making an assumption about weight distribution.

Personally, the best thing I can do to improve fuel economy would be to avoid rush hour. Leaving earlier (or later) to avoid stop/start on the highway is a major contributor to fuel economy.

I'm about to get an mk3 5spd hatch. What kind of rpm's are manual mk3 owners getting on the highway, say around 65,70, and 75mph?
Also, what do you guys think about putting it in neutral and coasting down big hills?

I've had a tank of 50mpg and 608 miles. I've made no modifications but this tank was while at Yellowstone NP where the max speed limit is 45mph. Speed is the most significant factor.

39 mpg is the best I've achieved with my stock '12 focus 5-speed base model. That's approx. %75 highway Illinois 55 . Lately 36 mpg, maybe the "blend "has changed. The best mpg was with Sam's club gas, the lower mpg was the cheapest gas I found at Thorntons. The mileage did increase as the car was used more ,I think at 25k miles the motor has broken in.

'Fraid the variations can get confusing, for our divisions here (just to keep 'em separate) yours would be considered a "Mk1.5", the first variant on the original.

Yeah, I missed the discrepancy in engine type. For a lower compression engine there should be no significant advantage to higher octane gas whereas the 12:1 compression ratio of the Mk3 Duratec engine will benefit from higher octane gas.

Has anyone considered vortex generators? Or has anyone done their own underside mid plate and rear diffuser?
